Don't Know How to Conduct Carbon Inventory for Four Industry Types? Taiwan EPA Releases New Calculation Tools and Carbon Inventory Guidelines!

Following the policy direction of the expanded carbon inventory announcement in March this year, Taiwan's Ministry of Environment released greenhouse gas inventory guidelines for four industry types on July 14, covering service industries, transportation, medical institutions, and universities. Additionally, a carbon emission calculation tool was introduced to help businesses preliminarily calculate their carbon emissions. This update is great news for regulated businesses, significantly reducing the administrative costs required for inventory operations. This article will reveal all the details of this information.

How Does This Announcement Help the Four Industry Types?

In response to the Ministry of Environment's expansion of "inventory subjects," among the four industry types mentioned, those meeting the conditions in Figure 1 below will need to report carbon emission data to the Ministry of Environment. Combined with the calculation tools and these "industry-specific" inventory guidelines, businesses can:

Preliminarily determine whether they are subject to regulation
Obtain clear and actionable assistance in inventory operations

How Does the Calculation Tool Determine If a Business Meets Regulation Conditions?

By selecting greenhouse gas emission sources and entering activity data, the calculation tool can help businesses generate Scope 1 and 2 carbon emission data. Combined with Figure 1 provided in this article, businesses can preliminarily determine whether they are subject to Ministry of Environment regulation.

What Are the Key Differences in the New Inventory Guidelines?

Compared to the Ministry of Environment's previously released "2024 Greenhouse Gas Emission Inventory Operation Guidelines," the carbon inventory guidelines for four industries released this time mainly demonstrate the following features in practical operation:

Targeted content design: Each carbon inventory guideline defines common emission sources and emission types for each industry based on operational characteristics. Even "inventory beginners" without experience can follow the guidelines to conduct inventory, helping users quickly grasp key points and reduce exploration costs.
Provides calculation methods for industry-specific special items: Reference materials for calculation methods related to special items in each industry are often difficult to obtain. These guidelines address this situation by providing clear carbon inventory operation instructions.

Regulatory Requirements and Reporting Schedule

If you meet the "inventory subject" conditions in Figure 1, you need to conduct greenhouse gas inventory operations, which means completing the 2025 carbon emission data inventory and reporting to the Ministry of Environment before April 30, 2026.

Where Can I Download the Guidelines?

The Ministry of Environment has publicly released greenhouse gas inventory guidelines for various industries, as well as calculation tools and operation manuals on the "Business Greenhouse Gas Emission Information Platform" for public use.

Carbon Inventory Regulations Are Here: What's Next for SMEs?

As the Ministry of Environment expands carbon inventory guideline announcements, it's clear that not only large enterprises but also small and medium-sized businesses will gradually be brought under management. Facing this trend, SMEs should refer to guideline content early, start inventorying data, and establish basic carbon inventory capabilities.

However, if you need not only preliminary carbon data calculations but also want to comprehensively grasp facility-wide carbon emission status and easily complete key tasks such as regulatory reporting and identifying emission hotspots, we sincerely recommend implementing Sustaihub's DCarbon Cloud Carbon System. This system can help you cover most inventory needs, significantly reduce administrative burdens, and effectively improve reporting efficiency to confidently respond to all Ministry of Environment requirements.

Carbon inventory doesn't have to start from scratch—combining appropriate digital tools is the key to standing firm in the carbon management era!
